Kenwood car amp troubleshooting, help appreciated!

post #1 of 2
Thread Starter 
I'm having a strange problem with my truck's sound system (diagram below)

It's pretty straightforward, the important thing is that they share a lead from the battery as well as a ground, which both split before going to the amps.

It worked fine for a few months, but I happened to be poking around and saw that the ground wire was coming disconnected from one of the amps, so I reconnected it. While doing so I accidentally tapped it to the +12v side, and now the amps will only flicker on for a split second before turning off again (simultaneously). I've checked all the fuses, redone all the connections, and been all over it with a multimeter checking voltages, and I can't find anything wrong.

As part of my troubleshooting I disconnected the battery lead and tried turning the amps on, and got the exact same flicker on and off. I'm guessing my hot lead's iffy; good enough to give me a voltage reading but not good enough to carry any amperage? I find it hard to believe that I fried an 8 gauge wire (Or maybe a 6, not entirely sure) in a split second without blowing the fuse by the battery.

Any enlightenment would be greatly appreciated, I'd like to figure this out without completely ripping out and rewiring my stereo...

Oh yeah, the amp models - they're the kenwood KAC-8105D and KAC-8405.

Oh nvm you already checked the fuses. I would check your cables, anything melted esp your ACC line. You might have an issue with the remote line.
